The line graph illustrates the number of people in different age categories in a particular country over a 80-year period, with the future estimates up to 2040.
Overall, old people will make up a great percentage of the population towards the end of the period, while the population of youth will decrease. The most common age will be from 15 to 65+, while only a mere percent of the population will consist of younger people towards the end of the period.
In 1960, around 57% of the population were people aged from 15 to 64. Since then, it had fluctuated before starting to decline slowly to reach 50% in 2020. It is predicted that the downward trend will continue to reach 45% by the end of the period. The population aged from 0 to 14 also experienced a decrease, albeit much more substantial. Starting from 30% in 1960, it has been decreasing steadily and is expected to reach 10% by the year 2040.
The population of elderly (65+) will experience a striking rise. In 1960, only roughly 15% of the population consisted of elder people. However, the number was and will be climbing to reach the same percentage level as that of people aged 15-64 by the end of the period.
